In the database, the storage of the index is usually implemented by using B-tree or + + trees, and the binary method is used to locate the data position quickly. Normal indexes are d

Vernacular spatial statistics: spatial autocorrelationSpatial autocorrelation, is certainly the space statistics inside the first stumbling block, a lot of people met this tall on the vocabulary, immediately found that these five words I seem to know, but in the end said what? I don't know.If open all kinds of textbooks, from statistics to mathematics to physics, all kinds of explanations have put up a pair

Original Spatial adjustment can be used to correct the location of a factor so that it can match the data in the database more accurately; it can also match the units of data obtained from a digital device or scanner to the units in the real world. It can also match low-precision data to high-precision data. Space correction tools include space transform, rubbersheet, edge match, and attribute transfer. Each tool has one option. This document takes th

Mysql supports spatial databases and uses HibernateSpatial for spatial data persistence. Hibernate 1. spatial data: if you develop maps, you will certainly be familiar with spatial data, that is, map elements, points, lines, and graphics, which have x and y coordinates. 2. mySQL supports

1. Spatial data: If you do the development of the map, then the spatial data must not be unfamiliar, that is, map elements namely, points, lines, graphs, they have x, y coordinates of information2.MySQL for the spatial database itself is support, but the support is not very comprehensive, in fact, the professional space database is not postgis, the reason for usi

Oracle Spatial's Spatial data applications are similar to those of Microsoft SQL Server 2008. SQL Server 2008 provides SQLCLR-based programming support, and Oracle Spatial does not yet have complete component support. In actual development and application scenarios, we can select a compromise solution, such as reading space data into a common space data expression format (such as WKT ), the open-source WKT

http://www.dengfanxin.cn/?p=403Original address I have translated the main parts of an important work on object detection, sppnet, in the paper. Sppnet's original intention is very clear, is that the network to the size of the input is more flexible, analysis to the convolutional network size is not required, the requirements of the fixed size is entirely from the whole connection layer, so the use of spatial pyramid pooling method to connect
